Feature request: Ability to embed GitHub gists

At the moment, it appears to be impossible to embed GitHub gists in WriteFreely posts. To embed a GitHub Gist in a blog post, one needs to copy and paste the embed code that GitHub provides, which is a <script>. It might look something like this:

<script src="https://gist.github.com/openjck/7085c782eda89c68f8f9.js"></script>

When I paste that into a WriteFreely post and publish the post, the Gist does not appear. When I go to edit the post, the <script> tag is still there, even though it’s not doing anything. Therefore, it appears the <script> tag is being stripped out by the renderer.

I’d like if these Gist <script> embeds were supported. Thank you!
